Summary

+ Reject unused arguments for `features` and `tweaks`
+ Reject unknown option flags for `clean`
+ Explain when `--keep` is missing its feature names

These changes address the ignored-argument cases in #58.

Evidence

• Before: On macOS 26.6.2 (25G83), features extra and tweaks bogus exited 0. clean --bogus --dry-run reported that --bogus was not in the cleanable list, and off --keep reported unknown option --keep.
• After: All four commands exit non-zero with the relevant argument or option error.
• Build: Debug and release builds passed with Swift 6.3.3; the release removemacai selftest passed all 85 checks. The CLI cases were run in an isolated macOS sandbox with networking disabled.

Merge Danger

Door: Two-way

Blast Radius: CLI argument validation. Extra arguments and unknown option flags now fail explicitly instead of being ignored or treated as names.

Summary by CodeRabbit

• Bug Fixes
  • Improved command-line validation: commands now reject unexpected arguments, and options report an error when their value is missing or looks like another option.
